Introduction

When it comes to security, your first line of defense is limiting the number of users who are authorized to access or modify your software's files and folders. In Windows, access control lists (ACL) enumerate the permissions each user has. A user in the list can either be granted a permission directly or inherit it by being a member of a Windows group. For example, being a member of the Administrators group gives full control to read, execute, and modify a file or the contents of a folder.

In this chapter, we will see how to set the ACLs of files and folders. We'll then talk about some other tricks that WiX has to offer, such as how to convert a regular folder into a file share and how to assign the default program to be used when opening a type of file.
